Operand Specifications
Description FIND$(660) finds the text string designated by S2 from within the text string
designated by S1, and outputs the result (a given number of characters from
the beginning of S1) in binary data to D. If there is no matching text string,
0000 hex is output to D.
Flags
Precautions The maximum number of characters to be read that can be designated by S1
or S2 is 4,095 (0FFF hex). If more than that are designated, an error will be
generated and the Error Flag will turn ON.
If 0000 (hex) is output to D, the Equals Flag will turn ON.
